Viimastel aastatel on ESA ja NASA \u00fchine kosmosesond SOHO aga n\u00e4idanud, et need \u201cm\u00e4\u00e4rdunud lumepallid\u201d on palju levinumad, kui keegi oleks osanud ette kujutada.<\/p>\n<\/div>\n<p>SOHO loodi P\u00e4ikese j\u00e4lgimiseks, mitte komeetide otsimiseks. \u00dcht selle instrumenti, nimega LASCO, kasutatakse P\u00e4ikese v\u00e4lisatmosf\u00e4\u00e4ri (korona) vaatlemiseks. Kuid just see on v\u00f5imaldanud SOHO-l saada ajaloo suurimaks komeetide jahtijaks.<\/p>\n<p>LASCO uurib n\u00f5rka korona, blokeerides P\u00e4ikese ere valgust. Juhuslikult v\u00f5imaldab see LASCO-l avastada ka v\u00e4ikeseid P\u00e4ikesele l\u00e4hedalt m\u00f6\u00f6duvaid komeete.
